There has been a remarkable run of record shattering heat waves in recent years, from the Russian heat wave of 2010 that set forests ablaze to the historic heat wave in Texas in 2011 and the Summer in March in the U.S. Midwest in 2012. These events typify the ongoing trend driven by climate change. Climate change is already affecting extreme weather. The National Academy of Sciences reports that ...

Although we often take it for granted, hearing is one of our most important senses. During infancy and childhood, hearing is vital for the normal development of speech and language. Hearing remains equally important throughout life as it enables us to communicate with friends and colleagues, and allows us to stay connected to and be aware of our environment. The ear is a remarkable structure, ...

The extreme weather phenomenon of heat waves poses a serious threat to humans and has been shown to contribute to increased sickness rates and even deaths, mostly in large cities. The paper concerns the occurrence of heat waves in Central Europe. Data was collected from five regional weather stations in Budapest, Krakow, Lvov, Prague and Vienna and included records of the average, maximum and ...

Few people have heard of Rossby waves and even less understand them, but if you are sweltering in an uncomfortably long heat wave, then they could be to blame. New discoveries about what is going on in the atmosphere are helping to explain why heat waves are lasting longer and causing serious damage to humans and the natural world. These events have doubled in ...

In recent years weather events have whiplashed between the extremes of heat and cold, flooding and drought. Carbon dioxide and other greenhouse gases—largely from the burning of coal, oil, and natural gas—have loaded up in the atmosphere, heating the planet and pushing humanity onto a climatic seesaw of weather irregularities. High-temperature records in many places are already being ...

One of the longest lived products in water resource monitoring has been the Stevens’ chart recorder. In fact, the chart recorder, originally invented by Stevens’ founder and namesake J.C. Stevens in 1911, is the product that established Stevens’ leadership in the water monitoring business. It’s no surprise then that some of these chart recorders have had long service lives and have recorded ...

In order to stimulate UK based marine energy technology developers, the UK Government launched the Marine Renewables Proving Fund (MRPF) in 2009. This instrument was designed to bridge the gap between early-stage research funding and the recently-criticised Marine Renewables Deployment Fund (MRDF). This paper develops an analysis framework for policy instruments designed to support technology ...

The first decade of the twenty-first century was the hottest since recordkeeping began in 1880. With an average global temperature of 14.52 degrees Celsius (58.1 degrees Fahrenheit), this decade was 0.2 degrees Celsius (0.36 degrees Fahrenheit) warmer than any previous decade. The year 2005 was the hottest on record, while 2007 and 2009 tied for second hottest. In fact, 9 of the 10 warmest years ...

For most of us power from the sea means watching waves crashing on a beach or smashing up against a breakwater. But if you want to experience wave power at its most energetic then you need to be offshore. In fact you need to be over one hundred kilometres offshore. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough, some 180Km from land, encountered the ...

About GPR Ground Penetrating Radar (GPR) is a non-invasive method of material analysis based on transmitting an ultra wide band EM signal into the materials. A part of the EM wave is reflected when it reaches a boundary between two materials with different electrical properties. The reflected signal gets recorded at the source of the EM wave and is displayed for the operator and ...

Proposed Gatun Bridge, Colon, Panama The Autoridad del Canal de Panama (ACP) conducted a geotechnical investigation along the footprint of a proposed bridge crossing of the Panama Canal, north of the Gatun Lock. As part of the geotechnical study, GeoView, Spotlight Geophysics and ATI Panamericana were tasked to provide seismic P-wave and S-wave velocity structure of the subsurface. The ...

Sound Quality and Vehicle Condition Research to evaluate sound signals inside trams has been undertaken using Brüel& Kjær binaural microphones, Time Data Recorder and PULSE data acquisition and analysis system. The tests were performed on a number of trams manufactured between 1908 and 2008, on normal town routes. Based on acoustical, spatial recordings, the initial quality ...

Northsea Wave and Level Measuring Station In the operation of the research centre coast of the NLWKN–Norden-Norderney Apart from the coastal engineering, the coastal surveying and morphology, the storm tide warning service of the NLWKN-Norden-Norderney belong to the specific questions and tasks of the coastal area. The German Wadden Sea and ...

LOG_aLevel Storm Tide Network at the Port of Hamburg, Germany Since 2003 a Storm Tide Network from General Acoustics GmbH (GA) has been satisfactory operating at the Port of Hamburg. In a first test phase of two years a LOG_aLevel station was successfully tested by the Hamburg Port Authority (HPA) against its conventional gauges. Due to the good results in terms of accuracy and ...

Tsunamis are extraordinary occurrences that are difficult to identify; most of the incidents have no recorded predictions and tsunamis are generally infrequent events with poor data acquisition. The development of a tsunami database system has become important for improving the management of information with regard to a tsunami early warning system for vulnerable communities along coastline ...
